Concord is a city of set stone — granite curbing, brick walks downtown, paver aprons and patios in the neighborhoods behind them. Paver Pros clears snow off surfaces like those with the attention they ask for, because a walkway laid by hand is not something to scrape at blindly. Drives get plowed, entries and paths get opened, and ice gets handled before it works its way down into a joint. There is a specific satisfaction in a shoveled path where the pattern of the stone shows again from door to street. Winter passes; the walkway is meant to still be there afterward.
